Revert "prohibit rcutorture from being compiled into the kernel" 

This reverts commit 9aaffc89.

That commit was a very bad idea. RCU_TORTURE found many boot timing
bugs and other sorts of bugs in the past, so excluding it from
boot images is very silly.

The option already depends on DEBUG_KERNEL and is disabled by default.
Even when it runs, the test threads are reniced. If it annoys people
we could add a runtime sysctl.

	  This option provides a kernel module that runs torture tests

	  on the RCU infrastructure.  The kernel module may be built

	  after the fact on the running kernel to be tested, if desired.



	  Say Y here if you want RCU torture tests to start automatically

	  at boot time (you probably don't).

	  Say M if you want the RCU torture tests to build as a module.

	  Say N if you are unsure.
